2.11 Connection of external devices
2.11.1 Connection of the 838 Advanced Sample Processor
The 838 Advanced Sample Processor, which is optionally available
from Metrohm, is an automatic sampler for ion chromatography. The
838 Advanced Sample Processor (RS232 interface) is connected to the
PC. The control programs are drawn up in the «IC Net» software. In or-
der to synchronize program sequences the 838 Advanced Sample Pro-
cessor and the 861 Advanced Compact IC are connected via the
6.2141.190 Remote cable.
Proceed as follows (after the connection of the 861 Advanced Compact
IC):
1 Electrical connection 838 – PC
•
Connect the RS232 interface of the 838 Advanced Sample
Processor to a serial COM interface of the PC using a
6.2134.100 Connection cable(9-pin/9-pin).
2 Electrical connection 861 – 838
•
Connect Remote connection 21 of the 861 Advanced Com-
pact IC and the Remote connection of the 838 Advanced
Sample Processors using a 6.2141.190 Cable (see 838 In-
structions for Use).
On Version 2.861.0040 the 853 CO
2
Suppressor is already
connected to Remote interface
. Connect the 6.2141.190
Cable to the rear of the Remote connector.
3 Tubing connection 838 – Injection valve
•
Screw off aspirating tubing 29 from injection valve 28 and
remove from feedthrough 4.
•
Cut the PEEK capillary tubing mounted on the 838 Advanced
Sample Processor to the required length (so that it can be
connected to injection valve 28 of the 861).
•
Pull the free end of the PEEK capillary tubing through open-
ing 8 of the 861 Advanced Compact IC and use a 6.2744.010
PEEK Compression fitting to screw it onto injection valve 28.
4 Tubing connection Injection valve – Waste
•
Insert 6.2744.020 Coupling (from the 861 accessories) into
connection 3 of the 861 Advanced Compact IC.
•
Screw aspirating tubing 29 into the 6.2744.020 Coupling and
insert into the waste container.
5 Setting up the 861/838 system
•
Select
File / Open / System
in the main window of the «IC Net »
software. Open the system for the 861 Advanced Compact IC
that you have created in Section 2.5.4.
